The Pteridium aquilinum is one toxic plant present in several countries of the world. The chronic ingestion causes diseases to livestock with negative economics repercussion. In Paraná state the Pteridium aquilinum is present in 105 out 399 municipal districts existents. The high occurrence of the plant in many areas of the Paraná state and the wrong utilization of these areas for cattle breed increase the importance of research that look for means that epidemic control of intoxication. Because that research institutions in the Paraná state have looking for means to advance in diagnosis methods, especially to cattle suffering from Bovine Enzootic Hematuria. The biomarkers have been used in the diagnosis and postoperative follow-up of tumor in the human beings in a routinely bases for years. Researches about this subject were crescent in the medicine of companion animals, however still incipient about cattle. Specifically in the Bovine Enzootic Hematuria were verified that mucin, a substance present in the mucus from the mucosal surface of bladder, is produced by tumoral cells in reasonable accounts. Previous reports verified one relationship between the excessive mucus protein production by the bladder with hemangioma and high plasmatic concentration of the sialic acid. This suggests that sialic acid is associated with inflammatory response of the tumoral growth, and might be used such as tumoral biomarker.
